SpringBoot启动报错信息：Failed to auto-configure a DataSource: ‘spring.datasource.url‘ is not specified... 骑猪看日落 2022-08-28 06:44 116阅读 0赞 ### Console报错如下： ### *************************** APPLICATION FAILED TO START *************************** Description: Failed to auto-configure a DataSource: 'spring.datasource.url' is not specified and no embedded datasource could be auto-configured. Reason: Failed to determine a suitable driver class Action: Consider the following: If you want an embedded database (H2, HSQL or Derby), please put it on the classpath. If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active). Process finished with exit code 1 -------------------- ### 解决方法： ### 需要在启动类的`@EnableAutoConfiguration`或`@SpringBootApplication`中添加`exclude= {DataSourceAutoConfiguration.class}`，即 `@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})` 排除此类的`autoconfig`。启动以后就可以正常运行。 **这是因为添加了数据库组件，所以autoconfig会去读取数据源配置，而新建的项目还没有配置数据源，所以会导致异常出现。**
还没有评论，来说两句吧...
